In this scenario, you start knowing there's a day limit, you have to help an outpost. To reach it in time you'll have to travel through an unexplored land. Resting in the game cost time and travel time depends of some parameters. Also during your travels there are multiple events that can make you lost or win time.

Well, I don't like if the entire game is time-based and this will not happen… you'll never lose the game just because you don't arrive on time… the game will just play differently depending on what time you arrive at different places.
